| Summary: | Stealth technology has developed very rapidly in the past few years, but still faces
serious bottlenecks, such as bandwidth, superluminal speed limit, dispersion, loss and
so on. In this dissertation, a stealth model which implanted epical stealth methods that
can combine all the technical metrics of all current major stealth strategies to solve the
bottlenecks of individual strategies has been designed and investigated.. A broadband
cylindrical stealth in free space is designed based on scattering cancellation (the
previous method for plasmatic stealth), together to validate practical fabrication
possibility using anisotropic metamaterials (a unique feature of previous transforming
optical stealth).
In this dissertation the tradition method has been combined with trend leading
technology Genetic Algorithm optimization method to help better confine the
constitutive parameter, proving that the machine learning algorithm do contributes to
excellent performance in all evaluating metrics.
On the basis of the GA (Genetic Algorithm) optimization algorithm, the
relationship between the inner boundary and the outer boundary and the wavelength,
the number of layers of the cloak design, and other parameters on the cloak's stealth
effect are also proved in this dissertation |
